Definitions
- the coil 19 only operates in transmit/receive mode but the operation is otherwise the same as for the coil of Figure 2.
- the embodiment is designed and intended to be mounted within or be otherwise carried by an interventional device for use with MR imaging equipment.
- an interventional device could be a catheter or a guide wire.
- the loop or coil of wire 19 is twisted on itself to form a twisted pair having two leads 20 and 21.
- the wire in this example is 0.25mm diameter with insulation having a thickness of 0.12mm.
- the twisted pair loop 19 is tuned to 21.3 MHz.
